MARION MAROELLUS SIOKLER, OF BUFFALO, NEW YORK.

ROAD-MAHINE Specification of Letters Patent.

Patented March 16, 19(29.

Application filed December 18, 1907. y Serial No. 407307.

To all whom it may concern:

Be it known that l, MARION M. SroxLER, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Road-Machines, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a road scraper of very simple construction, and which may be made very light and strong, and one that can be advantageously used upon mountain roads.

It is a further purpose of the invention'to provide means for steering the machine under ordinary conditions, and auxiliary steering means that act in conjunction with the main steering means, enabling the machine to turn sharp corners or curves, since it can be turned practically in its own length.

Another purpose of the invention is to provide means for turning the scraper blade at any desired angle to the line of draft, and independent means for inclining the scraper blade in direction of either end sovas to cause the blade to cut deeper at one end than at the other.

A further purpose of the invention is to provide means for shifting the draft so that said draft can be applied practically parallel with the line of travel of the machine no matter in what position the scraper blade may be, and also to provide means for raising and lowering` the scraper blade.-

The invention consists in thenovel construction and combination of the several parts as will be hereinafter fully vset forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming. a part of this specification, in which similar characters of reference indicate corresponding parts in all the claims.

Figure 1 is a side elevation of the machine; Fig. 2 is a plan view; Fig. 3 is a front elevation of the machine; Fig. 4 is a detail section taken through the auxiliary steering and lifting device practically on the line 4-4 of Fig. 1; and Fig. 5 is an enlarged detail sectional view of the rear portion of the bed of the machine where the auxiliary steering and the lifting mechanism are `located, showing portions of both of said mechanisms.

` A represents the bed of the machine which is by preference wider at the front Athan at the rear, and the said bed A at its forward end is supported by an axle B having vertically disposed clip bearings 10 at its end portions, as is shown in Fig. 3, and in these clip bearings 10, vertical members 11 of supplemental T-axles B are pivoted, and the forward supporting wheels 13 are mounted to turn upon an outwardlyl extending hori- Zontal member 12 of said supplemental axles, as is also best shown in Fig. 3. Thus it will beV observed that the wheels are mounted to turn upon the supplementalr kmain forward axle B.

At the upper end of the verticalfmember 11 of each supplemental axle B', above the upper members of the clip bearings 10, a sprocket wheel 14 is secured to the said supplemental axle and the said sprocket wheels are connected by a chain belt 15, as is also shown in Fig. 3. `One of the su pleinental axles B', preferably the right-han one, has a vertical shaft 16 secured tothe up er end of its vertical member, and the sai shaft 16 passes up through a bearing 17 at a forward cornerof the bed A, and the shaft at its u per end carries a hand -wheel 16a. y means of the shaft 16 and its accompanying hand-wheel 16?L the machine may be steered as far as ordinary purposes are concerned, but an auxiliary steering device is provided adapted to' co-act with the main forward steering device just described,which vsu lemental or auxiliary steering device willpbe described in detail. Y f

` The direct communication between the forward end of the bed A and the main axle B is obtained through the medium of an arched member O, which is provided with a cross bar 18 about centrally between the top and the bottom, and a pivot pin 19 is passed through the central portion of this cross bar in the forward central end portion of the bed A, as is shown in Fig. 3, a boss 2O surrounding the opening through which the pin 19 asses. At each end of the arched member an eye or a bearing 21 is produced, through which the axle B is loosely passed and at the upper or crown portion of the arched member O, rack teeth 22 are produced, which teeth are engaged by a pinion 23, and the said pinion 23 is secured upon a shaft 24 that is mounted over the forward central portion of the bed A in bearings 25 and 26 secured to said bed, and a hand-wheel 27 is located at the inner end of the aforesaid shaft 24. This shaft 24 and its accompanying pinion are ada ted to so move the bed as to give the' scraper lade D an inclination in .direction of either one or the other of its ends, and the said scraper blade is provided with a concaved fo`r'\`vard, and a convexed' rear face. This scraper blade is secured to' or isV carried by the lower portion of a ring-'like turn-table 28, mounted for rotary movement in a ringlike support 29, .that is located in a suitable the bed A, as is shown in Fig. 2. The ringlike turn table 28 is provided at its rear portion with interiorly located rack teeth 30 for a purpose to be hereinafter mentioned, and' braces 3l extend from the under face of the said turn table, and these braces- 31 support a post 32 atthe central portion ofthe turn table, which post extends vertically downward, as is illustrated in Fig. 1. The scraper blade D is secured to a shoe 33 correspondingly shaped, `which shoe is secured in its turn preferably to the braces of the turn table 23 in front of the post 32, and arms 34 are carried from the rear of the shoe 33 upward to an engagement with the rear under portion ofthe said turn table 28, as is illustrated in F ig. 1, and the central; arm 34 may be also secured to or may receive theA lower end of the post32. The rear end of thebed A is supported by a single wheel 35 which is a pivotal or caster wheel. ConsequentlyA when the shaft 24 is turned in one or the other direction causing the pinion 23 to travel over the teeth 22 of the arched member the bed A will be tilted in direction of one side or the other, and consequently one or the other end of the scraper blade D will be depressed.

A draft bar 36 is pivotally attached to the up er end portion of the aforesaid post 32, an the said draft bar 36 extends some distance beyond the forward end of the machine', and is provided with a suitable clevis 37, or other means for attachment to a draft device. At the other end portion of the draft bar 36, an upwardly extending socket .38 is formed and through this socket and through the said draft bar, the lower end of ashaft3'9 is passed, being suitably supported in said soc ret, and the said shaft is provided at its upper end with a hand-wheel 40, and at its lower end with a pinion 41, the said pinion 41 being adapted for engagement with theteeth of a horizontal segmental rack 42 that extends from one lower portion of the arched member C to the other, at a point below its center, as is illustrated best in Figs. 1 and 3, and the said draft bar 36, which is capable of movement beneath the bed from side to side, has movement at its outer end over theupper face of the said arched rack 42. This rack 42 and accom anying pinion 4l and shaft 39 are utilize to overcome the side draft of the scraper blade Dy when said scraper blade is at an angle to the line of draft, since at such time the tendency is for the machine' to slide in direction of the side where the end of the scraper blade is nearest the front, and to overcome this tendency the shaft 39 is operated to carry the draft bar 36 sufficiently far in an opposite direction, or in the' direction of the rearwardly inclined end of the scraper blade, to obtain a draft practically parallel with the longitudinal axis of the 3 machine, or the line of travel. recess produced in the central under face of An opening 43 is made in the bed A at the central rea-r portion, which opening is shown in Figs. 2 and 5. jring-like support 44 is secured to the under 1 face of the bed and in this support a turn table 45 is mounted to revolve, being preferj ably of ring-like construction, as is indicated Ein lfig. 5, and this turn table 45 has exterior 'teeth 46.

Below this opening 43 a A pinion 47 is attached to the lower endof an upwardly extending vertical shaft 48, which shaft 48 at its upper portion,

as is shown in lig. 1,- is passedthrough the horizontal branch arm of a vertical standard 50 that rises from a base 51 secured upon the up er face of the bed, and the shaft 48is provi ed at its up er end with a bevel gear 52. A second stan( ard 53 is located in front of the standard 50, being' connected therewith by an arm 54, and in the upper end of these two standards 50 and 53 a horizontal shaft 55 is mounted to turn, provided at its rear end with a bevel pinion 56- that meshes with the bevel pinion 53 on the shaft 48, and at the forward end of the shaft 55, a suitable handwheel 57 is secured. Thus by turning the hand-wheel 57, the turn table 45 may be given motion in the desired direction.

The lower b'ifurcated end portions 58 of an upwardly and forwardly extending bracket D are secured in any suitable or approved manner to each side of the central portion of the turn table 45. VThe bracket D extends beyond the rear of the bed A, as is particularly shown in Figs. 1 and 2, and in its end portion-a transverse slot 59 is produced, as is shown in Fig. 4, and in the end portions of this slot bearings 60 are formed. The forward straight section 61 of` a skeleton segment E is passed through the turn table 45 between the members 58 at the lower end of the aforesaid bracket D, as is illustrated best in Figs. 1 and 5, and this member 61 of the said segment E is pivotally attached to the said turn table45 through the medium of a downwardly extending web 63, for example, as is shown in Fig. 5, the pivot pin for the segment being designated as 62. The curved rear portion of the member 64 of the said segment E is made to slide freely in the transverse slot 59 at the rear end portion of the bracket D', and the rear edge of the said segment E is provided with teeth 64a that are engaged by a worm 65 located between the bearings 60, as is shown best in Fig. 1, which worm is operated through lthe medium of an upwardly and forwardly extending shaft 66 secured thereto and provided at its upper end vdtlia hand-wheel 67.

The lower portion of the segment E, or that portion that is below the bed A, is bifurcated to receive between its members the rear supporting wheel that is provided with a suitable spindle 85a. That portion of the segment E that isl provided with teeth 6aa is likewise provided with aseries of apertures 69, and these apertures are adapted to receive a locking pin 70, shown in Figs. l and 4, operating through the medium of a suitable lever 7]. that extends preferablyparallel with the shaft 66, the lever being provided with a suitable fulcruin 72 carried by the said bracket D. When the shaft 66 is operated it will raise or lower the segment E, causing the bed A to move in a corresponding direction, and consequently either raise the scraper blade D from the ground or cause it to enter the ground to a greater or lesser depth, and the bed A is then held in adjusted position through the medium of the lever 71 and the locking 'pin 70. lf it is desired to turn a very sharp corner, or around a very abrupt curve, the segment E operating in connection with the turn table 45 and operating through the medium of the shafts 48 and 55, can be turned simultaneously in a reverse direction to the direction in which the forward wheels are operated by the main steering gear, thus causing the machine to turn quickly, and permitting it to turn practically in its length.

The main turn table 28 is made to carry the scraper blade D to desired position rela tively to the line of travel of the machine in the following manner: A pinion 78, shown in dotted lines in Fig. l, meshes with the teeth 30 at the .inner rear portion of the turn table 28. This pinion 7 3 is secured to a shaft 7 4 that is journaled in the connecting bar 54 between the standards 50 and 58, and the shaft 7 4 is provided with a hand-wheel 75 at its upper end, and after the turn table 28 has been adjusted it is held in position by a pin 77 that passes down through the bed and into one of a number of apertures in the turn table 28, the said pin being preferably carried by a foot lever 7 6, as is illustrated in Fig. 2.

From the foregoing description it will be observed that the forward steering gear is independent of the other mechanisms and that the supplemental rear steering gear, while independent of the main steering gear, may likewise be used concertedly therewith, and that the supplemental rear steering mechanism can be independently used for raising and lowering the scraper blade.V It is also evident that the mechanism for changing the line of draft is independent in its action, as is the means for inclining the scraper blade endwise and the means for adjusting the scraper blade in position relatively to the line of draft. All of these mechanisms are within easy control of persons standing on the bed A and are exceedingly simpleV in their character. Y
